PS Audio Digital Link III low output level on one channel

[vicdiaz]

Hi,

After being unused for several years I powered up my PS Audio DLIII DAC and the output of one of the channels is very low compared to the other one. Has anyone experienced this? Any tips on what to check? Schematics anyone?

Thanks in advance,

Vic

Doesn't look like PS Audio publishes that information. Probably they expect you to send it back to them for repair, if needed.

Sadly they don't repair it anymore.

If you can post a good, clear hi-res pic or pics of the pcb (good enough to read part numbers on components) then maybe some useful advice could be possible. Hard to say without seeing the board first.

According to the article below it uses custom transistor based I/V converters, so I suspect a dodgy transistor. Perhaps a cool-spray might help find the culprit if you're lucky.
